What is dev-dashboard?

A command that starts the dev-dashboard web server, a local website for viewing development information, and shows its browser address.

Use it to open or launch the dev dashboard, reuse an existing server, start a new one on localhost, and stop it with the bundled stop command.

It handles checking whether the dashboard is already running and finding another available port when needed. This avoids manually starting the server or locating its URL.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00046	$0.00401
Opus 5	$0.00023	$0.00200
Sonnet 5	$0.00009	$0.00080
Haiku 4.5	$0.00005	$0.00040

Security

Grade A, and why

dev-dashboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (dashboard/client/assets/index-BXvuNVOi.js, dashboard/client/sw.js, dashboard/server/index.cjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Start Dev Dashboard

Start the dev-dashboard server (or reuse an existing instance) and display the URL. The dashboard runs entirely from the bundled launcher in this skill — there is no ~/.local/bin install step and no command shims to manage.

Step 1: Launch

Run the bundled start script directly by absolute path:

bash "$SCRIPTS/start.sh" --open

Where $SCRIPTS is the absolute path to scripts/ within this skill's directory. Use $HOME instead of literal home paths.

start.sh resolves the bundled server relative to its own location, reuses an already-running instance if one is found (matched across plugin versions), or starts a fresh one on the configured port (falling back to a nearby free port). --open also opens the dashboard in the browser. The server binds to 127.0.0.1 (localhost only) by default.

To stop the server, run the bundled stop script:

bash "$SCRIPTS/stop.sh"

Step 2: Parse Output and Report

The launch command outputs one of:

running:<port> — server was already running
started:<port> — new server started
error:<message> — something went wrong

On success, display:

Dev Dashboard: http://localhost:<port>

If it was already running, add "(already running)".

On error, show the error message. If the error came from the launch command, suggest checking /tmp/dev-dashboard.log.

Files

What ships with it

14 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
